Questions for Scathach

1) I can't help you on hassan, I don't use it.
2) AQB is better for NP gain.
3) If I have to choose between those two, I would say Imaginary Around because it's a 25% gain on all her Quick cards (including NP), more all-round than an increase of NP damage by 40%.
4) A good team composition : Waver to help her get to 100% NP, Jack The Ripper or someone who can feed her with critical stars or you can go all brutal with Berserkers like Heracles or Gintoki to kill everyone with buster chain (not recommended for high level challenges).

1) if you dont have jack or MHX this is the best star generator right now
2)for NP gain is better ABB with 28% of gain wihtout count overkill effect, the AQQ gives you 26%
3)Situational, sometimes i put Halloween princess, to get the np faster, imaginary around to get more stars, Heaven's feel is for shoot her NP in 1 turn with a lot of buffs
4) i have mi shishou with Jack (Crit generator) Waver to NP gain and crit boost, if you dont have Waver use Andersen for Crit boost. Atalante is a nice option to buff her NP

I hope this help you and sorry for my english.
